vue能循环一个固定变量嘛？比如说我num=3我要循环num次<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Document</title><script src="https://unpkg.com/vue@2.3.3"></script></head><body><div id="app"> <div v-for="n in full"></div> <div v-if="ishalf"></div> <div v-for="n in empty"></div></div><script> const MAXSIZE = 5; var vm = new Vue({ el : '#app', props: { score:{ type: Number, defualt: 4.5 } }, data:{ num : 3 }, created(){ this.full = Math.floor(this.score); this.ishalf = this.score!=this.full; this.empty = Math.floor(MAXSIZE-this.score); } })</script></body></html>
